NAMM 2013: We've been hanging out with Alex Skolnick a lot lately: One day, we're talking to him about his 10 essential guitar albums; the next, we're hooking with him at NAMM to get the lowdown on his new signature amp from Budda Amplification.

The AS Preceptor is a three-channel, high-gain head that the Testament guitarist developed to meet his diverse, ever-evolving needs – meaning it can handle thrash metal, jazz, world music and no doubt anything else.

There's a boatload of sonic goodies featured in the AS Preceptor (including a nine-channel MIDI foot controller – very nice), and in the video above, the man himself explains them all and demos some of the sounds.
